We consider 1D lattices described by Hubbard or Bose-Hubbard models, in the presence of periodic high-frequency perturbations, such as uniform ac force or modulation of hopping coefficients. Effective Hamiltonians for interacting particles are derived using an averaging method resembling classical canonical perturbation theory. As is known, a high-frequency force may renormalize hopping coeffic...

THIS short book consists of nine lectures given at a recent symposium in the University of Edinburgh. The topics cover a wide range of interest from nutrition in the fetus to nutrition in the elderly. Most of the chapters are well written and give an overview of the subject. The general conclusion from reading the book is that there is little evidence that malnutrition in general or deficiences...

ACKNOWLEDGEMENTS I want to thank my adviser, Dr. Magnus Egerstedt, who spurred my interest in graph grammars and modular robotics through his course on networked control. His feedback and guidance throughout my thesis research were invaluable. I also want to thank my family for their continuous support and encouragement in my pursuit of my Master's degree.

Dux magnus gentis venteris saginati is considered to be a Scottish delicacy; however, depleting wild stocks have resulted in attempts to farm them. Selective breeding has been successful in modifying behaviour, increasing body length, reducing hair coat and improving fank (litter) size. However, there are still significant problems associated with the terrain in which they are farmed. This arti...

Azaleothrips, a phlaeothripine genus of fungus-feeding species, is presumably endemic to the Oriental Region between India and Japan. Although only 10 species have been known in this genus until now, a total of 35 species is recorded here, of which 26 are newly described: from Indonesia--A. bali sp.n., A. bulelengi sp.n., A. dentatus sp.n., A. dorsalis sp.n., A. floresi sp.n., A. inflavus sp.n....

Antidiscrimination policies play an important role in public discussions. However, identifying discriminatory practices in the labor market is not an easy task. Correspondence testing provides a credible way to reveal discrimination in hiring and provide hard facts for policies. What is this instrument? What does it show and how reliable is it? Should it be widely used for policymaking? Answers...

In anesthetized rats, opioid analgesia is accompanied by a specific pattern of tonic activity in two neuronal populations within the medullary raphe magnus (RM): opioids silence pain-facilitatory ON cells and produce sustained discharge in pain-inhibitory OFF cells. These tonic activity patterns, hypothesized to generate a tonic analgesic state, have not been observed in recordings made without...

Protein L is a multidomain cell-wall protein isolated from Peptostreptococcus magnus. It belongs to a group of proteins that contain repeated domains that are able to bind to Igs without stimulating an immune response, the most characterized of this group being Protein A ( Staphylococcus aureus ) and Protein G ( Streptococcus ). Both of these proteins bind predominantly to the interface of C(H)...

The effects of stimulating locus coeruleus (LC) and nucleus raphe magnus (NRM) on lumbar dorsal horn cells that had been denervated by dorsal rhizotomy were studied. Both LC and NRM stimulation inhibited the responses of dorsal horn cells from the side of the cord with intact dorsal roots. However, when cells from the side of the spinal cord that had had prior rhizotomies were studied, half of ...
